Hi, AjaxFormLoop seems intended for formitems and would require a lot of javascript wiring to make it do what I want it to do. All I need is for the Form to completely ignore the Loop, just like it did nicely in 5.0.18. Do you know why the Loop's state needs to be persisted in the first place? And why can I not tell it to be completely ignored by the Form?
It seems to me that all this state saving on a loop is needed if there are formitems in the loop. If so, it'd be great if I could just ignore the whole state saving and use the Loop in a nice and simple way by setting something like ignoreForm=true.
